2.1.1 Subject to Changes
WAGO Kontakttechnik GmbH & Co. KG reserves the right to provide for any
alterations or modifications. WAGO Kontakttechnik GmbH & Co. KG owns all
rights arising from the granting of patents or from the legal protection of utility
patents. Third-party products are always mentioned without any reference to

2.1.2 Personnel Qualifications
All sequences implemented on WAGO-I/O-SYSTEM 750 devices may only be
carried out by electrical specialists with sufficient knowledge in automation. The
specialists must be familiar with the current norms and guidelines for the devices
and automated environments.
All changes to the coupler or controller should always be carried out by qualified
personnel with sufficient skills in PLC programming.

Fieldbus couplers, controllers and I/O modules found in the modular WAGO-I/O-
SYSTEM 750 receive digital and analog signals from sensors and transmit them
to actuators or higher-level control systems. Using controllers, the signals can
also be (pre-) processed.
The devices have been developed for use in an environment that meets the IP20
protection class criteria. Protection against finger injury and solid impurities up to
12.5 mm diameter is assured; protection against water damage is not ensured.
Unless otherwise specified, operation of the devices in wet and dusty
environments is prohibited.
Operating the WAGO-I/O-SYSTEM 750 devices in home applications without
further measures is only permitted if they meet the emission limits (emissions of
interference) according to EN 61000-6-3. You will find the relevant information in
the section “Device Description” > “Standards and Guidelines” in the manual for
the used fieldbus coupler or controller.

Manual
Version 1.4.1
Appropriate housing (per 2014/34/EU) is required when operating the
WAGO-I/O-SYSTEM 750 in hazardous environments. Please note that a
prototype test certificate must be obtained that confirms the correct installation of
the system in a housing or switch cabinet.
The implementation of safety functions such as EMERGENCY STOP or safety
door monitoring must only be performed by the F-I/O modules within the modular
WAGO-I/O-SYSTEM 750. Only these safe F-I/O modules ensure functional
safety in accordance with the latest international standards. WAGO's
interference-free output modules can be controlled by the safety function.

2.1.4 Technical Condition of Specified Devices
The devices to be supplied ex works are equipped with hardware and software
configurations, which meet the individual application requirements. These
modules contain no parts that can be serviced or repaired by the user. The
following actions will result in the exclusion of liability on the part of WAGO
Kontakttechnik GmbH & Co. KG:
• Repairs,
• Changes to the hardware or software that are not described in the
operating instructions,

The 750-461 I/O module measures resistance at field level or evaluates platinum
or nickel resistance sensors.
The resistance values are converted into temperature values. A microprocessor
in the I/O module linearizes the measured resistance values and converts them
into a numeric value proportional to the temperature of the selected resistance
sensor.
